One of the important problems is when "Use entire disk" is selected , some of the installers are still searching valid partitions on disk and failing miserably because there does not exist any one ( because unit is new or corrupted ) or there are some partitions , etc. remained from another different operating system . My opinion is that the first question should be to select an option among "Use entire disk" or "Use existing file systems" . alternatives , only search valid file system(s) when "Use existing file systems" is selected . When "Use entire disk" is selected , directly apply file systems creations by just after determining the geometry of the unit under consideration . Thank you very much . Mehmet Erol Sanliturk
